There's the NVidia Shield. Well, unless by "real" you mean "more than 10 people will actually buy it".

That is one potential definition of the term, sure, but first and foremost probably is simply "a system which you can buy games for in stores that sell videogames."

Technically, the NVidia chip used here is ARM just like the 3DS, so it SHOULD be the same architecture as the previous systems, but it wouldn't surprise me if it lacks a handful of instruction sets from the ARM Holdings chipset that prevent full fledged backwards compatibility. That's a shame.

NVidia's mobile chips use an ARM variant too? Huh. But yeah, that's possible, or maybe Nintendo just doesn't care about handheld BC on this system. Or maybe it actually is possible, they just won't admit it now because they want people to still buy the 3DS and if the Switch was clearly a 3DS replacement that would undermine 3DS sales? That seems plausible too...
